Maanantain sähkön koviin lukemiin on useita syitä, kertoo Energiateollisuuden sähkömarkkinoista vastaava johtaja Pekka Salomaa.

Pörssisähkön hinta pomppaa maanantaina poikkeuksellisen korkealle, kun verolliset hinnat käyvät useita kertoja yli 50 sentissä kilowattitunnilta.

Sähkön hintaan räjähdysmäinen nousu – Tähän aikaan se on kalleinta
Korkeimmillaan hinta on kello 13.45.

Pörssisähkön hinta nousee maanantaina poikkeuksellisen korkealle. Hinta kallistuu heti aamusta lähtien nopeasti.

Korkeimmillaan hinta on kello 13.45, kun varttihinta kapuaa 52,15 senttiin kilowattitunnilta.

Hinta käy päivän aikana useamman kerran yli 50 sentissä kilowattitunnilta, ensimmäisen kerran kello 10.30.

Ex-ministeri Lintilän (kesk) mukaan nyt pitäisi valmistella esitys maakaapeloinnin määräajan pidentämisestä, sillä sähkön siirtohinnat uhkaavat nousta roimasti. ”Ellei mitään tehdä, kasvavan laskun maksavat suomalaiset kotitaloudet”, Lintilä sanoo.

Nyt verkon toimitusvarmuudelle asetettu takaraja on vuonna 2036, mikä uhkaa Lintilän mukaan lähes tuplata joillain alueilla siirtohinnat tavoitteeseen pääsemiseksi. Kuluerot sähkönsiirrossa lasketaan maantieteellisesti jopa sadoissa euroissa, Lintilä huomauttaa.

Sähkönhintateorian kehittäjä oli akateemikko, matemaattinen taloustieteilijä ja poliittisesti oikeistolainen Marcel Boiteux. Hän oli myös EDF:n l. maailman suurimman sähkölaitoksen pääjohtaja. Marcel vastusti tiukasti EU:n ajamaa energiapolitiikkaa todetem, että sähkö on poikkeusala johtuen tuotannon monopolistisesta luonteesta, suurtuotannon eduista, tarvittavista valtavista pääomista, kysynnän joustamattomuudesta ja tarpeesta joka hetki tasapainottaa tuotanto ja kulutus ja totesi, ettei markkinamekanismi toimi näistä syistä oikein ja seuraus on korkeat hinnat, tolkuton hintojen heiluminen ja mahdottomuus tehdä pitkän aikavälin vaatimia investointeja. Marcel myös totesi, että verkot on rakennettu tukeviksi ja pieni määrä tuuli- tai aurinkovoimaa sopii hyvin, mutta jos tällaisen sääriippuvaisen tuotannon määrä kasvaa yli 10% tulee siirtoverkko suunnitella kokonaan uudestaan. EU:ssa tämä kustannus on nyt arvioitu 2000 miljardiksi. EU:n kuitenkin voitettua, kysyin Marcellilta mitä hän nyt ajatteli, vastaus kuului: Le mal esta arrive, pahin on tapahtumut.

Finland solved nuclear energy’s hardest problem first: burying radioactive waste safely for a hundred thousand years.

Finland runs some of the most reliable nuclear reactors in the world, providing a steady share of the country’s electricity through dark, freezing winters. The Olkiluoto plant on the west coast hosts multiple reactors, including a modern unit that strengthens the nation’s energy independence. Nuclear power runs day and night regardless of weather, giving Finland dependable low-carbon electricity when hydropower reservoirs freeze and the sun barely rises.

What truly sets Finland apart is its approach to nuclear waste. Deep beneath the forests of Olkiluoto, engineers have excavated a network of tunnels and caverns designed to hold spent fuel for an extraordinary span of time. The Onkalo repository encapsulates fuel rods in copper canisters surrounded by bentonite clay, sealed inside bedrock deep below the surface. It is the world’s first permanent geological repository of its kind, decades in the making and built through careful public consultation with local communities.

This long-term thinking has earned nuclear energy broad public support in Finland, where the technology is seen as a pillar of climate action rather than a controversy. As other countries debate how to handle their own waste, Finland’s example shows that the problem is solvable with patience, engineering rigor, and honesty. The quiet Finnish reactors keep humming, proving that nuclear can be one of the cleanest and most dependable tools in the energy mix.

Norway’s power lines are quietly wiring Europe for a cleaner future.

High above the fjords, where waterfalls have powered Norway for more than a century, a new kind of export is flowing — clean electricity carried across mountains and under the sea to neighboring countries. Thick subsea cables link Norway’s hydropower reservoirs with neighboring grids, letting water stored in mountain lakes act like a giant battery for the region. When the wind drops over the North Sea or the sun sets over the continent, Norwegian hydropower steps in within minutes, filling the gap with renewable power.

Building and maintaining this network in such dramatic terrain is an engineering feat. Transmission towers march across ridgelines, through tunnels, and along narrow fjord edges where the weather can turn in minutes. Specialized crews work at height in rain, snow, and biting wind, keeping the lines alive through long Arctic winters. Every new connection demands careful planning to protect the fragile northern landscape, balancing the hunger for clean power with respect for the wild places the cables cross.

The result is a grid that does more than light Norwegian homes. It steadies neighboring power systems, absorbs their excess wind and solar when they produce too much, and returns stored hydropower when they need it most. In a continent racing to decarbonize, Norway’s transmission web has become quiet infrastructure for everyone — built wire by wire across borders.

Norway’s electricity system is overwhelmingly renewable, dominated by hydropower with wind and solar providing additional generation.

Official Statnett data shows Norway produced about 154 TWh of electricity in 2023, including nearly 14 TWh from wind power. Hydropower remains the backbone of the system, with reservoirs providing flexibility by storing water and releasing it when electricity demand is highest.

One important distinction: the often-circulated 99.8% figure depends on the dataset and definition used. NVE’s 2023 climate declaration reported 95% of physically delivered electricity as renewable after accounting for electricity imports, while national electricity-generation datasets put Norway’s renewable generation share around 98–99%.

Norway’s system demonstrates how abundant hydropower, large reservoirs, transmission infrastructure and additional wind generation can produce a very low-carbon electricity mix. It also relies on connections with neighboring countries, so it should not be interpreted as complete energy independence.

Finland put smart meters in nearly every home ahead of most of Europe. Coverage reached 100 percent years ago, and households have been billed on actual readings since 2014.

A smart meter records electricity use in short intervals and reports it automatically, replacing the old routine of manual readings and estimated bills. Paired with hourly pricing, it turns the abstract wholesale market into numbers a household can actually act on, hour by hour.

That visibility changes behavior. Many Finns check day-ahead prices each morning and run washing machines, heat pumps, or car chargers when power is cheapest. Multiplied across a country with heavy winter heating demand, those small shifts add up to serious money saved.

The grid benefits too. When thousands of households shift usage away from peak hours, strain on the system eases and the need for expensive backup plants shrinks. Personal savings and national grid stability turn out to be two sides of the same coin.

Finland is already planning its second generation of meters, with even finer data for the next phase of electrification. The lesson for other countries is simple: the smartest grid starts with giving every household a clear window into its own power use.

Finland has transitioned from hourly to 15-minute electricity metering and pricing as part of a broader EU-wide electricity market reform.
